nGen-FLEX is a semi-flexible material with good printability on most 3D printers eliminating the use for specialized flex extruders. It’s rated at a Shore A hardness level of 95. By adjusting infill and perimeter settings it’s possible to influence how flexible a part should feel after printing. nGen_FLEX is temperature resistant to about 125 °C. That means 3D printed objects can be steam sterilized at 121 °C.
